Just 5 minutes ago I was thinking about a "memory benchmark" to find out
how much memory a scalar/array of scalars/Math::Pari/Math::GMP object
takes. having a simple way to access and print this would rock, otherwise I
would need to do ugly stuff like allocating 100000 and then looking at top
to see how much memory it uses.
The idea is great! Can I have it? I won't mind:
use statistics qw/memory_usage/;
use Foo;
my $a = Foo->new();
print memory_usage($a),"\n";
print statistics::live_time($a),"\n";
or whatever.
Thanx!
